The last_interval variable could potentially be used before being first
assigned a value.

So this can happen only if grouping is [0] (or an equivalent iterable).  
Since this is an invalid grouping, I think the appropriate response would 
be for _grouping_intervals([0]) to raise an exception (which is what it 
currently does as soon as you iterate over the result, though this is 
possibly not by design. :)

Vincent, does the attached patch (_grouping_intervals.patch, against py3k) 
silence the pylint warning?

Yes it does

Thanks.  Committed in r74312 (trunk), r74313 (py3k).
